I started masturbating regularly at the very young age of 6 and continue to this day. By the time I reached puberty I had experienced many dry orgasms. By the age of 13 I had experienced numerous "wet" orgasms so I knew about cumming. One afternoon I was in my bedroom leafing through my favorite Playboy (we didn't have the luxury of internet porn back then). My parents were downstairs locked to the TV watching their favorite show so I figured I would "play with my favorite toy". I was lying on my back on my bed with my eyes closed happily stroking my hard cock. All of a sudden I heard a loud gasp. I opened my eyes to see my 9 year old sister standing in my doorway with a shocked look on her face. She was a nosy, little brat too curious for her own good. "Close the door": I screamed, meaning for her to leave. I closed my eyes and returned to pleasuring myself. To my shock and surprise she closed the door behind her and stayed in my room "What are you doing to your "thing" and why is it bigger than normal": she asked. She had accidentally seen me naked a couple times before so she knew what my cock looked like soft, but she'd never seen it hard. I figured the only way to get rid of her was to explain what I was doing. I explained to her that I was jacking off and my "thing" always got bigger and harder when I stroked it. "Why do you do it": she asked. "Because it feels good and when you do it for a while it feels really good and the some special juice squirts out": I said. By this time I'd lost my hard on and I was eager to return to my self imposed state of bliss. "Look, it's normal again": she said. "Will it grow again if I do it": she asked? Figuring I could get some payback for her rude interruption I told her I wasn't sure, but she could try. She walked over to the edge of my bed and stared at my flaccid cock with amazement. "I've never seen one this close":she said. "Well see if you can make it grow": I demanded. Befuddled she asked:" How do I do it"? I told her to gently grab it with her hand and slowly slide it up and down the shaft. She reached over and grasped my flaccid cock in her tiny hand. I immediately felt the blood start to flow back into my flaccid cock. " Oh look, it's starting to grow already":she giggled. "Keep it up, it gets bigger": I said. She was slowly stroking away as my cock reached full hardness. I saw a look of awe and amazement in her eyes as she slowly stroked away. She really seemed to be enjoying playing with my favorite toy and I was enjoying it immensely too. I was amazed at how wonderful it felt having her little hand massaging my hard cock and my excitement was rapidly growing. My breathing was getting shallower and my muscles were starting to tense. "Is that it, is that all": she asked in disappointment? "I want to see it squirt":she demanded. I told her to keep stroking it was almost time. My breathing quickened and my legs started to twitch as my orgasm quickly approach, I knew I was gonna cum within moments. "Lean your head over my stomach and look directly at the tip on my "thing", but don't stop yet": I instructed. She eagerly obliged my request. All of sudden I gasped for air, my body began to tremble and I reached nirvana. With my little sister still stroking my cock, I unleashed my full load right into her awestruck face. She never stopped, she kept pumping away until she had milked the last drop of cum out of my now flaccid cock. To my surprise and disappointment she wasn't even mad about her first unexpected facial. After regaining my composure I noticed her take her cum cover hand and raise it to her lips. I chuckled as I looked at her cum cover face and saw her cautiously lick my cum from her fingers. "It's slimy and kinda salty. What is it": she asked? I told her boys called it jizz as I wiped my cum from her face with one of my t-shirts. I told her that was the all and that she could leave, but she could never tell our parents or I'd never let her watch me again. To the day they died my parents never knew their little girl got her first facial from her big brother. So I got my revenge on my nosy sister, but to my disappointment she seemed to really enjoy it.
